Faculty
Dr. Doreen Riepel ist Tenure-Track Faculty am CISPA Helmholtz-Zentrum für Informationssicherheit. Ihre Forschungsschwerpunkte liegen in den theoretischen Grundlagen der Kryptographie und der beweisbaren Sicherheit, insbesondere in der Analyse und Entwicklung kryptographischer Verfahren und Protokolle. Sie arbeitet unter anderem zu authentifiziertem Schlüsselaustausch, sicherer Kommunikation, Public-Key-Verschlüsselung mit zusätzlichen Funktionalitäten, Post-Quantum-Kryptographie und formalen Sicherheitsbeweisen. Zuvor war Doreen Postdoktorandin an der University of California, San Diego. Ihre Promotion schloss sie an der Ruhr-Universität Bochum unter der Leitung von Prof. Dr. Eike Kiltz ab.
